Q2501B OpenAT Application Stop


#1

Hi,

I’m using Firmware 6.55. I have an application that connect with a server socket. When the server is not working the module does some resets by the external watchdog pin. Thats ok.
When you run the server application the modules reconnect but I meet some modules that the code does’nt run. It seems the code is inside but nothing happens after a reset.
The command
at+wopen?
+wopen:1
so the OpenAT is running.

if I type at+wopen=3 and at+wopen=4 the answer is Ok so the code is ok.

The only way to solve the problem is to reprogram the module

What’s wrong for to reach this state?

Thanks in advanced
